Slicklines
Sandvik wire products acquired by Zapp AG
Sandvik’s wire business has been acquired by Zapp AG from August 31, 2018. Over the coming months Zapp will be integrating the Sandvik portfolio, to provide a smooth transition for customers. During the integration period, the full line of Sandvik wire products will continue to be accessible on this website, or via the Zapp website.
Please note: divestment of wire products does not include EXERA fine wire and medical wire components manufactured by Sandvik Palm Coast.
Wire for slicklines in a wide range of stainless steels and high-alloy materials, suitable for both sour and sweet wells.
Sandvik's wide range of materials for single-strand slicklines makes it possible to select the most appropriate grade for a specific environment. This contributes to safer operations and longer service life.
Cut costs with stainless steel slicklines
Although a higher initial cost, stainless steel slicklines can provide significant savings compared to carbon steel slicklines which are more susceptible to failure and lost production time.
Even in wells of moderate corrosive conditions, a stainless steel or high-alloy slickline will provide a significantly longer life, meaning:
- Less downtime in the well
- Fewer slicklines to be purchased
- Fewer slicklines to be re-spooled

| Sandvik SAF 2507 (UNS 32750) |
For service in highly corrosive oil and gas wells. Excellent resistance to stress corrosion cracking (SCC) in chloride and CO2 environments. Excellent resistance to pitting and general corrosion in chloride and acidizing environments. Breaking loads are very high. |
| Sandvik SAF 2205 (UNS S31803) |
For service in corrosive oil and gas wells. High resistance to stress corrosion cracking (SCC) in chloride and CO2 environments. High resistance to pitting and general corrosion. |
| Sandvik 5R60 (UNS S31600, ASTM 316) |
For service in less severe corrosive oil and gas wells. Good resistance to general corrosion. |
| Sandvik CS-9A | A high-strength carbon steel suitable for use in sweet oil and gas wells. |

User's guide
User's guide for slicklines
Correct handling will prolong the life of the slickline and reduce the overall cost.
Recommendations for slickline usage:
- Avoid abrasion between the line and the ground or other equipment
- Ensure that sheave grooves are of the correct diameter
- Check sheaves for wear
- Check that sheaves are able to rotate freely
- Check the rubber seal in the stuffing box for wear
- Check the seal or gland in stuffing box for wear
- Use caution during jarring operations
- Inspect lines for diameter reduction after heavy jarring
- Brake carefully when lowering tools into the well
- When re-spooling, always spool from top to top
- Avoid kinking the line
- Avoid damage to shipping spools
- Store wireline spools vertically
- Clean lines after use
Recommended safe load
We recommend a safe load of 75% of the effective breaking load.
- Breaking load = certified tensile strength x diameter2 x 0.7854
- Effective breaking load = breaking load minus tool weight minus line weight
Wraptor ductility testing unit
With Sandvik's Wraptor ductility testing unit it is possible to more accurately predict the retirement point of a slickline. This leads to considerable cost savings through the reduced risk of unplanned production stops and the loss of valuable production equipment. Read more about Wraptor ductility testing unit
